Application that May 15, 1900.

To all whom it may concern.-

Be it known that we, GOODWIN AMBROSE BLAUVELT,1esidin g on Marion street,and DA v11) WINFIELD ORANSTON, residing at No. 4 South Broadway,Nyack, county of Rockland, and State of New York, citizens of the United States, have invented certain new and useful Improvements in AcetyleneGas-Generating Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate corresponding parts in both figures.

This invention relates to an improved gasmachine adapted especially for generating and distributing acetylene gas, the objects thereof being to provide an efficient apparatus of this character which is automatic in action and continuously effective in operation and which is simple in construction, safe, and durable.

The invention will he hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying drawings,forn1ing part of this specification, Figure l is a vertical axial sectional view of our newly-invented gas-generating machine, and Fig. 2 is a detail vertical sectional elevation taken on the line 9300 of Fig. 1.

A designates the walls of the tank in which the apparatus is inclosed and which contains the customary water seal, as 1, common to gasometers. Within this tank is a floating gasometer B of the usual cylindrical form.

C and O designate guides on which the rollers b and b of the gasometer move in the usual and well-known way.

WVithin the floating gasometer B is a gen-. erating cylindrical tank E. This inner generating-tank is supplied with water, which flows in through the feed-pipe e and may be emptied through the pipe 6 by means of the valve e In the top of the gasometer B is a handhole D, which may be of any approved construction and by which entrance is aflorded into the said gasometer for the purpose of charging the device with a gas-producing carbid, as will be hereinafter described. A rod F passes through a stuffing-box F in the top Serial No. 16,729. (No model.)

B of the said gasometer, so that it will be partly in and partly out of the gasometer, and its ends are bent at right angles, as illustrated byfand f.

G designates a tubular entrance, by which access is given to the interiorof the hopper or carbid receptacle II. This tubular e11- trance is flanged outwardly at its top, and 011 this flange is placed the elastic gasket g. This opening is norm ally closed by the threaded plug 9, and said opening leads through the upper Wall H of the hopper or receptacle H at one side. This receptacle H is partly cylindrical and partly conical of the form illustrated in axial section, Fig. 1 of the drawings, and it is provided interiorly with a conical partition H which has apertures it there through for feeding carbid to the generatingtank E.

Extended diametrically across the top of the receptacle H is a lever M, pivoted at M to a projection on the'top H of the carbidreceptacle H. One end of this lever M carries the weight m. At m the lever M is connected by a short rod m to the rod N. This rod N extends downward through the tube h of the receptacle H and carries the valves N and N, which are adjustable on the rod N for the purpose of placing them in proper relative position. The valve N moves freely on the rod and tests by gravity on the pin 2, and the valve N is maintained in place by the nut 3. The end of the lever M opposite the weight m extends some distance horizontally in the receiver to engage the rod F, as will be hereinafter described.

The receptacle H is provided at its top with projecting plates 4, which engage lugs 5 of the generating-tank E, and the two said parts are connected by means of screws 6, whereby the receptacle can be readily removed, if desired.

The generating-tank E communicates with the gasometer B through the pipe 19. The gasometer B communicates with the servicepipes by means of the tube 19. At the bottom of the generating-tank E the trap S is placed to prevent the escape of gas when the water is low in the tank during the operation of emptying and refilling the same. The whole device rests upon a pedestal, (illusa es moe trated by T,) which may be of any convenient and approved form.

As a means for gaging the level of the water within the generator E a pan Q is employed, which pan communicates with the pipe (2' by means of a tube q.

In the operation of the device the water is introduced into the exterior tank A through the funnel-shaped inlet X to form the seal 1.

All the various parts of our newly-invented gas-generating machine are intended to be substantially as is illustrated in the drawings; but we do not confine ourselves to the specific details of mere mechanical construction, as it is obvious that under the scope of our invention we are entitled to slight structural variations.

To use our' invention, the water is drawn from the tank E and the gasometer B allowed to rest by gravity upon the gasket g, the inner extension f of the rod F being turned away from the end an of the lever M, whereby the weight 'm seats the valve N-in position within the outlet h of the receptacle H to prevent discharge of carbid therefrom while it is being filled. The hand-hole D is then opened and the plug 9 removed from the inlet G, which permits of the receptacle H being readily filled with carbid. Calcium carbid in suflicient quantity is now introduced into the receptacle H through the hand-hole D and the tubular entrance G. During this operation the elastic gaskets g, pressing against the top plate B, will prevent any escape of gas. through the hand-hole D from the gasometer B, and the valve N will prevent any of the calcium carbid from falling into the water in the generating-chamber E. As soon asthere has been a sufticient quantity of calcium carbid deposited in the receptacle H the entrance G and the hand-hole D are closed and water is introduced into the generator E through the inlet eand into the tank A through the funnel X, which operation floats the gasometer B to a suificient extent to permit of turning the extension f of the rod F across the end 1% of thelever M,whereby when pressure is reduced the weight of the gasometer will press the lever M downwardly and open the valve N" to discharge carbid. It will now be found that as the calcium carbid falls into the water in the generatingtank E and the gas is formed this gas will pass through the pipe 1) into the gasometer B, raising it up as the pressure increases. The lever M being free to move, the counterpoise-weight m will bear down that end of the lever and by means of the connection m and the rod N draw up the valve N upon its seat. As soon as this occurs the flow of calcium carbid from the receptacle H will be stopped and the pressure will remain stationary until the volume of gas is reduced by burning or otherwise. Then the pressure being less the gasometer B will sink down and bring the end f of the rod F into contact with the lever M. This will open the valve N", and the calcium carbid will again begin to fall into the water in the generating-tank to produce more gas and restore the pressure. These operations will thus continue until the supply of gas-making material has been exhausted. The loosely-mounted valve N acts to prevent a too-rapid discharge of carbid and as a safety-valve to be automatically seated over the outlet 71 in the event of the connec tion breaking and dropping the rod N and valve N within the generator.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a gas-generating machine, the combination with an outward gasometer constructed, arranged, and adapted to move upward and downward as specified, and a revoluble bent rod mounted in the top of said gasometer, of a generating-tank, within the said gasometer, a lever pivoted on, the top thereof, a counterpoise-weight upon one end of said lever, the other end of said lever extended so as to be capable of engaging the bent end of the rod aforesaid, another'rod carrying valves at its lower end, and at= tached by a short rod to said lever at its upper end, a receptacle for gas-generating chemicals within said generating-tank, means for depositing such materials in said chamber, valve-seats in the bottom of said chamber, upon which work the valves aforesaid, to regulate the passage of chemical material from said receptacle into said generatingtank, and a tubular guide in which said last- .named rod moves, all substantially as and for the purpose set forth.

2. In a gas-generating machine, the combination with a gasometer adapted to move upward and downward, a revoluble stop journaled through the top wall of said gasometer, an outer water-tank surrounding the gasometer, an inner generating-tank, a superimposed receptacle, for containing gasproducing chemicals, means for inlet and outlet of chemicals, valves for opening and closing the outlet of said receptacle, and a weighted rod-and-lever mechanism for operating the said valves, the said revoluble stop adapted to be arbitrarily turned for contact with the lever of the closing mechanism, substantially as shown and described.

In testimony that we claim the foregoing as our invention We have signed our names, in presence of two witnesses, this 12th day of May, 1900.
